So, let me get this straight: You seriously believe that black voters think about this, and not the many, many other reasons (healthcare, urban issues, etc) that they have legitimate policy disagreements with the Republicans on?
Believe it or not blacks do think about more than one thing at a time... It's not an either or situation, and the birtherism, baseless attack on Shirley Sherrod, and the auctioning of a rifle to celebrate MLK day all contribute to black voters turning away from the Republican party.
Hey but like I said, no need to argue. We'll just let the polls do the talking.
The GOP needs to up its game when it comes to black outreach. And we need to do that by changing certain issue positions, not by running token black candidates. Sure, that worked when we ran Allen West in 2010 here in FL-22, and some idiots in my party think that will repeat itself.
Rand Paul has been very good on reaching out on issues like DC Statehood (more of an issue for African Americans in DC, and not nationwide of course) and the war on drugs. States like Mississippi and South Carolina are seeing their black populations increase IIRC, and that could make these states swing states by 2032 in the same way that GA will be one in 2016.
But to imply that black voters make their decision to vote Democratic not on the issues that affect them, but rather the President's skin color and an auction involving a gun is ludicrous.
